PRODUCTION DATA.
When it is configured for DDR termination applications, REFOUT generates the DDR VTT reference voltage for the memory application. It is capable of supporting both a sourcing and sinking load of 10 mA. REFOUT becomes active when REFIN voltage rises to 0.390 V and VIN is above the UVLO threshold. When REFOUT is less than 0.375 V, it is disabled and subsequently discharges to GND through an internal 10-kΩ MOSFET. REFOUT is independent of the EN pin state.
